ROBERT H. KLEISER, OF DE WITT, ARKANSAS.

GRAIN-SCOURING MACHINE.

Application filed October 29, 1913.

To all whom it may concern:

Be it known that 1, ROBERT H. KLEISER, a citizen of the United States,residing at De \Vitt, in the county of Arkansas and State of Arkansas,have invented new and useful Improvements in Grain- Securing Machines,of which the following is a specification.

This invention relates to machines for scouring and cleaning rice andother grains, and it has for its object to simplify and improve theconstruction and operation of this class of devices.

An object of the invention is to provide the brush member with flexiblestops to prevent grain from working down between the bristles withoutpassing in active contact with the screen.

WVith these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

In the drawings,Figure 1 is a side elevation, partly in section, of amachine constructed in accordance with the invention. Fig. 2 is a detailview partly in section and partly in perspective showing a portion ofthe brush member. Fig. 3 is a vertical sectional view taken on the line33 in Fig. 1. Fig. 4 is a sectional detail View illustrating amodification.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The improved machine includes a scouring member A of conical or frustumshape, said member being mounted base upward on a shaft 15. The member Ais composed of annularly flanged heads 16, 17 holding and clampingbetween them a plurality of staves 18 having bristles 19 of wire orother suitable material. The heads 16, 17 are connected by clamping rods20. The shaft 15 is stepped at its lower end in a socket 21 formed in asupporting bar 22 carried by vertically adjustable screw threaded rods23 Specification of Letters Patent.

Serial No. 798,082.

"that extend through a floor or platform 24% and are provided with nuts25, whereby adustment may be effected.

Supported above the floor or platform 24: by means of legs or uprightsis a casing 27 through which the shaft 15 extends and within which issupported a conical screen 28 that surrounds the brush member A, saidscreen being supported and reinforced in such a manner as to enable itto efficiently resist wear. The screen 28 is concentric with the memberA, and the space between the latter and the screen may be varied byvertical adjustment of the shaft 15 by the means described. One or morebearings for the shaft may be provided, as indicated at 29, in additionto the step 21.

The scouring member A is provided with one or more annular bands orflanges 30 formed of leather or other suitable flexible material, eachof said bands bein of a width substantially equal to the length of thebristles. These bands may be secured by means of fastening members, suchas spikes 31, driven into the staves 18 and havlng forked heads 32wherein the band may be retained by fastening means, such asa rivet 33.Any other convenient means for mounting the flanges 30 may, however, beemployed, as shown for example in Fig. 4, where the flange 30 has beenshown as being mounted on an L-shaped bracket member 10. It will beobserved that the flanges 30 do not extend beyond the bristles 19 sothat said flanges will not obstruct the space between the brush memberand the screen; the flanges, however, will obstruct the interspacesbetween the bristles, thus making it impossible for any grain to workdown between the bristles without coming into contact with the scouringsurface of the screen.

A driving pulley 31 adapted to receive motion from any convenient sourceof power may be mounted in any available position on the shaft 15. Aninlet spout 35 is provided whereby the grain to be operated upon will bedischarged on the head 16 at the upper end of the scouring member.Receiving hoppers 36 and 37 are also provided through which the cleanedgrain passing over the screen and the bran and impurities that aredischarged through the screen, respectively, may be spouted to a placeof deposit.

In the operation of this invention, the shaft carrying the scouringmember A is rotated at a desired speed, and the grain that is to bescoured is discharged on the head 16, whence it is distributed bycentrifugal action in the direction of the screen 28. The grain passingdown inside the screen will be subjected to thescouring action of thebrush, and the'bran and impurities be-" ing thus removed will passthrough the screen and the casing and be discharged into the hopper 37.Any grain attempting to work down through the inter-spaces between thebristles will be checked or intercepted by the flange or flanges 30 andwill be compelled to pass into the space between the brush and thescreen where it must of necessity be subjected to a scouring action. Theclean grain will be discharged from the screen into the hopper 36.

It is obviousthat in the construction of a machine based on theprinciple of this invention, any desired number of units may beemployed, and that such units may be arranged side by side in tandem orother relation, it being also feasible to arrange several units invertical series, thus enabling a plurality of scouring members to bemounted on a single shaft. Any such arrangement would obviously bewithin the" scope of the present invention.

'Having thus described the invention, what is claimed as new, is-

1. In a machine of the class described, a cone-shaped scouring membercomprising annularly flanged upper and lower heads, staves fittedbetween said heads and having bristles constituting brushes, clamp rodsconnecting the heads, and an annular resilient flange surrounding thescouring member and projecting between but not beyond the bristles.

2. In a machine of the class described, a cone-shaped scouring membercomprising annularly flanged upper and lower heads, staves fittedvbetween said heads and having bristles constituting brushes, clamp rods.copiel of this patent may be obtained for jecting between but notbeyond the bristles, in combination with a cone-shaped screensurrounding and concentric with the scouring member, a vertical shaftcarrying the scouring member, and means for effecting adjustment of theshaft to vary the space between the scouring member and the screen.

t. In a machine of the class described, a scouring member of circularcross section supported for rotation and having radially extendingbristles, in combination with an.

annular flange supported in the interspaces obetween the bristles, saidflange being of a width approximately equalto the length of thebristles, and a screen of circular cross section surrounding, concentricwith and spaced from the scouring member.

5. In a machine of the class described, a scouring member of circularcross section supported for rotation and having radially extendingbristles, in combination with an annular flange of flexible materialfitted in the interspaces between the bristles, and supporting membersfor the said flange having forked heads wherein the flange is mounted.

In testimony whereof I ailix my signature in presence of two witnesses.
